Reciprocal effect in maize refers to the phenotypic difference between reciprocal F1 hybrids.
The aim of this study was to estimate influence of reciprocal crosses on grain yield and eight
yield components. Five single-cross hybrids, their reciprocal crosses and six parental inbred
lines were selected and all hybrids belong to late maturity group (FAO 500-600) with Lancaster
ZPL-7 line as mutual parent. The experiment was set up in two replications using a completelyrandomized block design in 2016 and 2017, at a total of seven environments. Reciprocal effect
significantly influenced only grain yield and ear length, while factors hybrid and location were
significant for all the examined traits. All hybrids individually displayed significant reciprocal
effect for grain yield, ear length, number of kernels per row and 100 kernel weight, two hybrids
for kernel length and thickness, while three hybrids showed reciprocal effect on kernel width.
The effects were both positive and neg...ative depending on the genotype itself. Furthermore,
there were no significant differences for ear row number and ear width between normal and
reciprocal variants. The highest difference for grain yield was between ZP 606 reciprocal
(12.06 t/ha) and ZP 606 normal (11.28 t/ha). Pearson correlations were calculated between
examined traits. All correlations between grain yield and other yield components were found
significant and positive, except for the number of rows per ear (no correlation) and kernel width
(negative correlation). Reciprocal effect has strong influence on the measured yield traits, but
it is genotype specific. Therefore, in the future we should examine normal and reciprocal
variants of all commercial maize hybrids.
